Session Files Suddenly Crashes on Startup: multiarch/strlen-avx2.S: No such file or directory

though rescan should clean out the log of previously found, now stale, LV2s)

That is why I was curious, since the plugin manager showed “Stale” state for all of the listed LV2 plugins.

Hopefully nothing.

Nothing happens. How do I trigger an LV2 rescan?

How do I trigger an LV2 rescan?

@ccaudle

you click the “Re-scan All” button?

As mentioned in my earlier post the plugin manager (the dialog in the screenshot you provided) has several buttons on the left hand side, one of which is labeled “Re-scan All.” Just click that button.

See above

LV2 plugins are indexed by meta-data at application start

LV2s are always and unconditionally indexed when loading a session or starting Ardour.

[RavenRandomz]

Do you think the program’s inability to index could be from two different liblilvs in conflict?

[peder (Peder Hedlund)]

Does lv2ls -n | grep -iE "nekobi|dragonfly|surge" show that it’s able to see your different plugins?
What does sudo ldconfig -p | grep lilv show?

Chances are your self compiled lilv is either buggy or something went wrong when you compiled and installed it.

@peder

lv2ls -n | grep -iE "nekobi|dragonfly|surge"

Nothing.

@peder

What does sudo ldconfig -p | grep lilv show?

This is shows even when I uninstalled both the apt version as well as the 0.24.24 compiled lilv.

rave@rave-machine:~/Documents/github/lilv$ sudo ldconfig -p | grep lilv
	liblilv-0.so.0 (libc6,x86-64) => /usr/local/lib/x86_64-linux-gnu/liblilv-0.so.0
	liblilv-0.so (libc6,x86-64) => /usr/local/lib/x86_64-linux-gnu/liblilv-0.so

That shows even if I ardour doesn’t start up from the lack of any lilv

rave@rave-machine:~/Documents/github/lilv$ ardour8
/usr/local/lib/ardour8/ardour-8.6.0: error while loading shared libraries: liblilv-0.so.0: cannot open shared object file: No such file or directory

When I manually install lilv, the command returns:

rave@rave-machine:~/Documents/github/lilv/build$ ldconfig -p | grep lilv
	liblilv-0.so.0 (libc6,x86-64) => /usr/local/lib/x86_64-linux-gnu/liblilv-0.so.0
	liblilv-0.so (libc6,x86-64) => /usr/local/lib/x86_64-linux-gnu/liblilv-0.so

When I compile and manually install lilv from here (the 0.24.24 tag that doesn’t cause the glitch):

Ardour suddenly becomes unable to detect lv2

When I install:

liblilv-0-0/noble,now 0.24.22-1build1 amd64 [installed,automatic]
  library for simple use of LV2 plugins

liblilv-dev/noble,now 0.24.22-1build1 amd64 [installed]
  library for simple use of LV2 plugins (development files)

Ardour can detect the lv2 plugins but since it’s 0.24.22, there’s the bug that randomly affects projects.

This is the build configuration for lilv that I use which allows me to open the affect projects, but causes the inability to detect l2v plugins

lilv 0.24.24

[peder (Peder Hedlund)]

Yeah, the problem seems to be that your compiled lilv only looks for plugins in

@RavenRandomz

Default LV2_PATH: ~/.lv2:/usr/local/lib/x86_64-linux-gnu/lv2:/usr/lib/x86_64-linux-gnu/lv2

but you actually have them installed in /usr/lib/lv2, as per your previous comment:

@RavenRandomz

rave@rave-machine:/usr/lib/lv2$ ls
 3BandEQ.lv2                       midifilter.lv2
 3BandSplitter.lv2                 midigen.lv2

The quick-n-dirty fix is to link ~/.lv2 to /usr/lib/lv2 by making sure you don’t have a ~/.lv2 folder and then run ln -s /usr/lib/lv2 ~/.lv2

Or you can recompile lilv after first configuring it with something like
meson setup -Ddefault_lv2_path=~/.lv2:/usr/lib/lv2:/usr/local/lib/x86_64-linux-gnu/lv2:/usr/lib/x86_64-linux-gnu/lv2:/usr/local/lib/lv2

[RavenRandomz]

Recompiled liblilv. It’s fixed, thank you everyone!!!
